OIL AND GASOLENE GENERATOR AND BURNER.

Specification of Letters Patent.

Patented Apr. 2, 1918.

Application filed August 23, 1917. Serial No. 187,834.

To all whom it may concern:

Be it known that we, IIENRYIIUNT and OSCAR S. PRICE, citizens of theUnited States, residing at Greentown, in the county of Howard, State ofIndiana have invented a new and useful Oil and (fasolene Generator andBurner, of which the following is a specification.

The device forming thesubject matter of this application is a combustiondevice adapted to be employed for turning liquid fuel, such as keroseneoil or gasolene, into gas, and the invention aims to provide novel meanswhereby the heating of the fuel, to turn the same into gas, is broughtabout.

Another object of the invention is to provide novel means whereby thegas may be mixed with air, and whereby a proper adjustment of thegas-supplying nozzle, with respect to the air inlet may be broughtabout.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that type to which the presentinvention appertains.

With the above and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed, without departing from the spirit of theinvention.

In the accompanying drawings Figure 1 shows in top plan, a combustiondevice embodying the present improvements;

Fig. 2 is a cross section taken on the line 22 of Fig. l;

r Fig. 3 is a side elevation of the combustion device shown in Fig. 1;

Fig. 4 is a fragmental longitudinal section through the mixing means;

Fig. 5 is a cross section taken on the line 55 of Fig. 4.

The device forming the subject matter of this application comprises aU-shaped conduit including lower members 1 and 2. The lower members 1and 2 are disposed in parallel relation and at the same level. Theconduit above mentioned includes upper members 3 and 4. The members 3and 4 are disposed in parallel relation, and at approximately the samelevel. A vertical connection 5 unites the inner end of the upper member3 with the inner end of the lower member 2. A vertical connection 6unites the inner end of the upper member 4 with the inner end of thelower member 1. The outer ends of the upper members 3 and 4 are unitedby an end tube 7 which is horizontally disposed. United with the outerend of the lower member 1 is a horizontal extension 8 in which isinterposed a valve 9, the valve 9 preferably being a needle valve. Theextension 8 projects toward the longitudinal center of the device, andits inner end is united with an elbow 10, carrying a nozzle 11 whichprojects, along the longitudinal center of the structure, parallel tothe elements 2, 3, 4 and 1. The nozzle 11 is supplied at its end with agas outlet 12. The nozzle 11 is externally threaded as shown at 14 toengage within a reducer 15 having a turning flange 16. The reducer 15 isthreaded into a larger reducer 17 hav ing a turning flange 18. Thereducer 17 is threaded into one end of a tubular mixing sleeve 19 havingan air inlet 20. One end of a burner tube 21 is threaded into the sleeve19 or is otherwise secured thereto. The burner tube 21 is disposedparallel to the elements 8, 4, l and 2, and preferably is arranged inthe same horizontal plane as the lower members 1 and 2 of the conduit.the burner tube extending beneath the end member 7 of the conduit. Theburner tube 21 is provided with orifices 23 which preferably areinclined laterally, so as to discharge toward the members 3 and 4. Theouter end of the burner tube 21 is closed by a cap 24. The outer end ofthe lower member 2 is provided with a lateral extension 25 carrying avalve 26 which may be a needle valve. By means of a coupling 27 thecasing of the valve 26 is connected with a so-called hollow wire 28whereby the fuel, such as gasolene or kerosene is supplied.

In practical operation, the fuel passes through the member 28 and iscontrolled by the valve 26. Thence, the fuel passes into the lowermember 2 and as the fuel rises in the connection 5, the conversion ofthe fuel into gas, under the action of the flames proceeding from theorifices 23 in the burner tube 21, begins. In the members 5, 3, 7, 4 and6, the conversion of fuel into gas is carried out, the gas traversingthe lower member 1 and passing by way of the extension 8, and the elbow10 into the nozzle 11,

the flow of gas being controlled by means of the valve 9. The gas passesout of the nozzle 11 by way of the outlet 12, into the sleeve 19, airbeing admitted into the sleeve through the inlet 20. In the sleeve 19, amixture of gas and air is efiected, and this mixture passes into theburner tube 21, the mixture burning in a plurality of jets at theorifices 23, these flame jets serving to heat up the elements 5, 6, 4, 3and 7, of the U-shaped conduit, to efiect a conversion of the liquidfuel into gas, as above described.

The position of the outlet 12 of the nozzle- 11 with respect to the airinlet 20 of the mixing sleeve 19 may be adjusted by rotating the reducer15, the nozzle 11 in this way being moved longitudinally with respect tothe mixing sleeve 19. Since two reducers 16 and 17 are employed, thereducer 15 may be omitted if desired, thereby permitting a larger nozzlethan the one shown in the drawings, to be threaded directly into thereducer 17. Since the connection 5 stands upright, the fuel supplied tothe lower memher 2 will be prevented from running, in liquid form, intothe parts 3, 7 and 4t. The construction of the device, therefore, issuch that it will be practically impossible to flood I the burner tube21 with liquid fuel.

Having thus described the invention, what is claimed is 1. In a deviceof the class described, a U- shaped conduit comprising approximatelyparallel lower members, approximately parallel upper members disposed ata higher elevation than the lower members; a tube a connecting the outerends of the upper members, and upright connections uniting the inlowermembers; and a source of fuel supplycommunicating with the outer end ofthe other lower member.

2. In a device of'the class described, a U-. V

shaped. conduit comprising approximately parallel lower members,approximately parallel upper members disposed at a higher elevation thanthe lower members, a tube connecting the outer ends of the uppermembers, and upright connections uniting the inner ends of the uppermembers with the inner ends of-the lower members; a tubular burnerdisposed between the upper members and between the lower members; anozzle connected with the outer end of one lower member; a reducerstructure threaded upon the outside of the nozzle; and a sleeve having alateral air inlet, the nozzle projecting into the sleeve to a pointadjacent to the inlet, the sleeve being threaded upon the outside of thereducer structure and upon the outside of the burner, whereby the sleevemay be grasped and rotated to adjust the position of the inlet withrespect to the inner end of the nozzle.

In testimony that we claim the foregoing as our own, we have heretoaflixed our signatures in the presence of two witnesses.
